“…The mass 2 TPD spectrum also shown in Figure 12, indicates H 2 evolution in the same temperature region as C 5 H 6 production. It is clear that the hydrogen desorption in this temperature region is reaction limited, as H 2 is observed to desorb from silver surfaces at temperatures < 200 K [40,41]. The data are, thus, consistent with the dehydrogenation of adsorbed cyclopentadienyl to give cyclopentadiene and H 2 through a disproportionation reaction:…”

“…According to Ref. [27,28] the Ag±H stretch is either at 60 (for Ag (1 1 0)) or at 100 meV (for Ag (1 1 1)). In our case this loss could be hidden by the peak at 69±71 meV assigned to the molecule±surface stretch.…”

Acetylene and Ethylene Hydrogenation on Alumina Supported Pd-Ag Model Catalysts

Adsorption and co-adsorption of ethylene, acetylene and hydrogen on Pd-Ag particles, supported on thin alumina films, have been studied by temperature programmed desorption (TPD). The TPD results show that adding of Ag to Pd suppresses overall hydrogenat ion activity but increases selectivity towards ethylene, i.e. similar to that observed on real catalysts. The results are rationalized on the basis of a complex interplay between surface and subsurface hydrogen species available in the system, whereby the latter species are the most critical for total hydrogenation of acetylene to ethane.
